(E 320 with sport package, E 430)
Important!
The spare wheel rim is mounted with a full size tire of
the same type as on the vehicle, and is fully functional.
However, that spare wheel rim is weight optimized and
has a limited service life of 12 000 miles (20 000 km)
use before a standard wheel rim must replace it.
In the case of a flat tire, you may temporarily use the
spare wheel.
Do not operate vehicle with more than one spare wheel
mounted.Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement.
If the arrow on tire side wall does not point in direction
of vehicle forward movement when using the spare
wheel, observe the following restrictions:
•Drive to the nearest tire repair facility as soon as
possible.
For rim and tire specifications, see page 317.
Wa r n i n g !
The spare wheel rim is for temporary use only. Use
for over a total of 12 000 miles (20 000 km)
(aggregate of f all uses) may cause wheel rim failure
leading to an accident and possible injuries.

cluster displayPractical hintsCar care Index If a tire constantly loses air, it should be inspected for
damage.
The spare tire should be checked periodically for
condition and inflation. Spare tire will age and become
worn over time even if never used, and thus should be
inspected and replaced when necessary.
Wa r n i n g !
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc.. Follow recommended
inflation pressures.Do not overload the tires by exceeding the specified
vehicle capacity weight (as indicated by the label
on the driver’s door latch post). Overloading the
tires can overheat them, possibly causing a
blowout.
